Title: Power-operated boosters for vehicle braking systems
IPC: B60T13/12
Filed: 1974-01-30
Abstract: 1481838 Hydraulic brake boosters GIRLING Ltd 13 Jan 1975 [30 Jan 1974 21 May 1974] 04302/74 and 22514/74 Heading F2F In an hydraulic brake booster having a piston 8 working in a bore 4 in a housing provided with an inlet port 11 for connection to a source of hydraulic fluid under pressure and an outlet port 14 for connection to a reservoir, the ports communicating through a valve with a power chamber 17 in the housing and the valve being so arranged that when the booster is operated fluid pressure in the chamber 17 advances the power piston, the valve includes a spool 18 working in complementary bores 12, 2 in the boost piston and in an adjacent end of the housing and the spool comprises an assembly of at least two separate parts 19, 20 which are in sealed abutment at adjacent ends, one part 20 working in the bore 12 in the piston 8 and the other in the bore 2 in the housing. When an input force is applied from a pedal to input piston 16 the spool assembly 18 is moved inwardly to initially cut off communication between ports 27, 28 and between power chamber 17 and a bore 25. Subsequent further movement of spool 18 opens a radial passage 13 to admit high pressure fluid to chamber 17 and advance boost piston 8 and since hydraulic fluid is trapped in boost chamber 29 movement of piston 8 is transmitted to output piston 30 and hence to pistons 42, 44 of the master cylinder to close recuperation ports 50 and pressurize fluid in spaces 45, 46. Upon failure of the high pressure source and/or failure of the power chamber 17 the spool assembly 18 moves through bore 12 to transmit directly to the piston 30 a force for operating the master cylinder. In modifications, Figs. 4 and 5, not shown, output pistons 30 are omitted and the pistons 8 operate directly on the operating rods 51 of the master cylinders so that no boost chamber is provided.

Title: Method and apparatus for the manufacture of fastening links for a sliding clasp fastener
IPC: B29D5/04
Filed: 1959-02-06
Abstract: 901,309. Sliding clasp fasteners. RUHRMANN, J., and BAUENDAHL, H., [trading as RUHRMANN, JOSEF (Firm of)]. Feb. 6, 1959 [Feb. 22, 1958], No. 4318/59. Class 44. [Also in Group V] A method for the manufacture of a continuous series of fastening links for a sliding clasp fastener comprises deforming a wire into serpentine form to present a continuous series of links, shaping the links so formed into U-shaped links by bending the serpentine form about a longitudinal axis thereof and then stamping the U-shaped links to form coupling elements at intermediate positions on the U-shaped links. As shown, wire 201 of elastically flexible synthetic material is fed from a spool 2 by means of a pair of rollers 30, 31 through an eye 4 to a slide 5 which is reciprocated in a direction parallel to the shaft of a shaping wheel 6. The slide winds the wire in serpentine form around laterally-disposed pins 61, 611 at the periphery of the wheel 6 and a holding device 7 acting in conjunction with the slide 5, moves to and fro perpendicularly to the shaft of the wheel 6. The wire is then passed under a member 8 and is lifted by wedge-shaped members 80. Simultaneously a constant speed shaping disc 9 presses a bridge section 202 of the wire structure into a groove 62 extending around the wheel 6 between the pins 61, 611, bridge section parts 203 being laid in recesses 63 provided in the groove 62. A punch 211 then acts upon a bridge section part 204 which lies in the base of the groove 62 to form a coupling element 205. The punch also includes shoulders which respectively engage projections 64 in the groove 62 and a part 206 of the wire structure. A further shaping disc 11 engaging the groove 62, removes burrs or irregularities from the wire structure. A heat-sensitive member 12 controls a thermostat 13 which regulates a heating coil 66 embedded in the wheel 6. The rotation of the wheel 6 is controlled by a check brake 14. The finished wire structure is cooled by an air nozzle 15 and is removed from the wheel 6 by a stripper 16. The machine is driven by a motor 18. The rollers 30, 31 which are of truncated cone form, constitute a uniform feed mechanism for the wire which passes between the roller surfaces and through eyes 34, 35 at opposite ends of a pivoted lever 32 prior to passing through the eye 4. Any variation in the tension on the wire at the eye 4 swings the lever 32 about its pivot, thus to move the wire along the surfaces of the rollers and so vary the rate at which the wire passes therebetween. A cog wheel 19 is rigidly connected to the wheel 6, through which pawls 191, 192 controlled by eccentrics 193, 194 driven from the motor 18 control the stepped rotation of the wheel 6. In some cases the wheel 6 may be driven continuously, the pawls then being dispensed with.

Abstract: 212,886. Jones & Laughlin Steel Corporation, (Assignees of Rendleman, N. C.). March 15, 1923, [Convention date]. Rolling flanged bars.-Flanged structural members such as I- beams and channels are rolled by a process wherein a series of rolling operations is performed on the mid portion of the billet to produce lateral spreading followed by a further series of rolling operations to reduce the flanges. An example is given of the rolling of a ten-inch I-beam 10, the thickness of the web being 1¢ per cent of the depth, and the width of the flanges 30 per cent of the depth. The section of the billet 13 is approximately 5 inches square and successive stages in the formation of the final product are shown in Fig. 4. The process may be carried out in two stands of three-high mills, Fig. 1 being a broken section through the lower pair of mating rolls of the first stand, and Fig. 2 a similar view of the second stand. The positions of the references A to H indicate whether the blank passes above or below the middle roll. In the second stand the rolls work on diagonally opposite flanges of the blank, at the same time separating them and reducing the web to increase progressively the depth of the beam. The shape of the final pass is such that the beam may subsequently be completed by a single pass in a universal or other type of mill. The process enables a beam to be completed at one heat.
